The '''Tektronix 465''' is a portable 100 MHz dual-trace oscilloscope with dual time-bases.  The 465 was very popular and Tek made them for quite a few years.  It is all solid-state except for the CRT.  It was introduced in November 1972.

It is all solid-state except for the CRT.  The 465 was very popular and Tek made them for quite a few years.  According to microfiche records, 37 variations of the 465 were produced.  


There was no 465A but a 465B (int. 1980) with the same base specs but improved performance.

The [[475]] is a 200 MHz sister model. See also [[465M]].


The optional [[DM44]] multimeter attaches to the top of the instrument.

[[Category:Specifications needed]] ''please add''
<blockquote>
Initial product planning and project coordination was provided by [[Leon Orchard]].
The mechanical design team for the 465 and 475, headed by [[Bob Rossman]], was: [[Neal Broadbent]], [[Bob Leith]], [[Len McCracken]], [[Bob Smesrud]], [[Ilmars Smiltins]], and [[Bob Twigg]].
[[Ken Holland]] and [[Bill Mark]] provided the attenuator design while [[Bob Johnson]] designed the [[P6065]] and [[P6075]] probes. Low-voltage power supply for the 465/475 was by [[George Ermini]], and [[Dennis Braatz]] designed the high-voltage supply. [[Connie Wilson]] and [[Gary Nelson]] did the CRT development.
 
Electrical design team assisting [[R. Michael Johnson]] in development of the 465 was: [[Frank Dewater]], [[Pete Janowitz]], [[Dave Laib]], [[Al Schamel]], and [[Bert tenKate]].
</blockquote>
 
[[Bill Turner]] worked as a calibration technician for the 465 oscilloscope group.
